Iyo wunvise 'AISI 8620 ishoramari', igitekerezo cyahise kuri benshi kijyanye nimiterere ya carburizing kubikoresho cyangwa shitingi. Nibyo, ariko kandi niho birenze urugero. Mubyukuri, kwerekana 8620 kuri casting ntabwo ari ugutora agasanduku k'ibikoresho ku gishushanyo; yiyemeje kumurongo wogukora aho ubuhanga bwumushinga mugukemura ibyuma biciriritse byibyuma bikomera biba ingirakamaro nka chimie ubwayo. Nabonye ibishushanyo byinshi binanirwa atari ukubera ko 8620 ari amahitamo atari yo, ariko kubera ko inzira yo gukina itajyanye nimiterere yihariye, biganisha ku gukomera kwimanza cyangwa kugabanuka guhishe. Ibi ntabwo ari ibintu byerekana; ni ikibazo cyamaboko.
Kamere ya Alloy hamwe no Kwiyunga
AISI 8620 nicyuma gikora nikel-chromium-molybdenum ibyuma, ishimirwa gukomera kwayo nigisubizo cyizewe kuri carburizing. Ariko, imyitwarire yayo yo gukina itandukanye nuburyo bwakozwe. Urufunguzo ni ugucunga karubone kuva yatangira. Mu gushora imari, gukonjesha byihuse ibice bito birashobora rimwe na rimwe kuganisha ku buryo bwiza kuruta uko byari byitezwe nk’abakinnyi, bikaba byiza, ariko kandi byongera ibyago byo kwanduza mikorobe niba sisitemu yo kugaburira no kugaburira idashyizwe muburyo bunoze bwo gukomera. Ntushobora gukoresha igishushanyo mbonera kimwe wakoresha mubyuma bya karubone byoroshye.
Ndibuka umushinga wamazu ya sensor yasabaga gukomera kwumuvuduko hamwe nubuso bwihanganira kwambara. Umukiriya yashimangiye aisi 8620 gushora imari. Ibyiciro bike byambere byatsinze igenzura ariko birananirana mugupima igitutu. Ikibazo? Micro-shrinkage. Ntabwo twari twabaze neza uburyo molybdenum yo muri 8620 ihindura gato ibyo kugaburira. Gukosora ntabwo birimo kwagura ibyago gusa, ahubwo kubisubiramo kugirango habeho gushimangira icyerekezo cyerekezo gikomeye. Twabibukije ko urupapuro rwerekana amavuta ruterekana imiterere yabakinnyi.
Aha niho uburambe bwigihe kirekire bwubushakashatsi butanga umusaruro. Isosiyete nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), hamwe nimyaka mirongo itatu muri shell no gushora imari, yaba yarubatse isomero ryamakuru nkaya. Bashobora kumenya, nkurugero, kuri 8620, ubushyuhe bwo gusuka bukenera idirishya rikomeye kuruta kubindi byuma bimwe na bimwe byoroheje bivanze kugirango bingane amazi nubunini bwingano. Nubumenyi bwa granular, inzira yihariye itandukanya casting ikora nubumenyi-bwizewe.
Aho Inzira ikora cyangwa ivunika igice
Ibyifuzo byo gushora imari mubice 8620 biragaragara: geometrike igoye, kurangiza neza neza, hamwe na net-shusho. Ariko igikonoshwa cyo gukora ubwacyo gikorana na alloy. Igikonoshwa ceramic kigomba kugira ubushyuhe bwinshi kugirango wirinde kwitwara hamwe na manganese na chromium muri 8620 mugihe cyo gusuka, bishobora gukurura ubusembwa. Igikonoshwa kidafite ubuziranenge cyangwa ubushyuhe butari bwiza mbere yubushyuhe burashobora kwinjiza karburizasi cyangwa decarburisation mbere yuko igice kijya mu itanura rivura ubushyuhe, bikajugunya ikibazo cyose gikomereye kubara.
Nyuma yo gukina, umuhanda uragereranijwe. Kugabanya imihangayiko hafi ya byose ntibishobora kuganirwaho mbere yo gutunganya, cyane cyane kubice bifite ibice bitandukanye. Nakoze ikosa ryo kuyisimbuka rimwe kuri prototype igice cyamaboko yo guhuza, nkeka ko as-cast yari muke. Igisubizo ni ukugoreka mugihe cyo gutunganya ibintu byakuyeho igice cyicyiciro. Igiciro cyurwo rugabano rwo kugabanya ibibazo ni gito ugereranije nigiciro cyibikoresho byakorewe.
Noneho haza kuvura ubushyuhe. Imyitozo isanzwe ni carburizing no kuzimya. Ariko ubanza bwa casting ireme itegeka byose. Niba hari ivangura rya dendritic cyangwa udutsiko duto duto dushyira mubikorwa byo gukina, kuzimya birashobora kubikabiriza, biganisha ku gukomera kutaringaniye cyangwa no kuzimya. Umufatanyabikorwa mwiza wo gushinga ntabwo azatanga casting gusa; bazatanga protocole yemewe yo kuvura ubushyuhe bushingiye kumiterere nyirizina. Duhereye ku bisobanuro bya QSY byo gukorana n'amavuta adasanzwe, ubu buryo bwo guhuza ibikoresho nibikorwa birashoboka ko ari igice gisanzwe cya serivisi zabo, kikaba ari ngombwa kubikoresho nka 8620 aho imitungo ya nyuma ikorerwa.
Imashini ya CNC: Kurangiza
Aha niho 'ishoramari' ryishura neza. Igice cyiza 8620 kigomba kugira amafaranga make yimigabane, ariko icyo kigega kigomba kuba kimwe. Imashini ya as-cast 8620 iratandukanye na mugenzi we wakozwe. Uruhu rwashizwemo rurakomeye kandi rushobora gukurura ibikoresho. Inzira ikomeye ikoresha ibice byoroheje kugirango icike uruhu mbere yo gukomeza gukora cyane. Kugerageza kubika umwanya ukoresheje ibikoresho bikozwe mubikoresho akenshi biganisha ku kwihuta kw ibikoresho hamwe nubusugire bubi bwubuso kumaso yanyuma yakozwe.
Kubigize nkibintu byogutwara umubumbe, ibinyamakuru byandika hamwe na spine byakozwe nyuma yo guterwa. Guhuzagurika gukomera kwa casting no kubura ubusa bwimbere nibyingenzi. Niba uburyo bwo gukina bwatangije ububobere buke munsi yubuso, pasiporo yimashini irashobora kuyifungura, bigatera kwangwa. Niyo mpamvu kugenzura inzira mugice cyishingiro ari ishoramari mugutunganya umusaruro. Utanga isoko atanga integuro gushora imari na Imashini ya CNC, nka QSY, ifite ibitekerezo bitaziguye. Itsinda ryabo ryimashini rirashobora guhita ryerekana inenge yongeye guterwa mumakipe yabo yashinze, bigafasha gukosora imizi iduka ryimashini yo hanze ishobora kuvuga nk '' itsinda ribi '.
Gukorana ni urufunguzo. Bashobora guteganya icyerekezo cya casting hamwe n’irembo aho bakoresheje ibikoresho bya nyuma byo gutunganya mu mutwe, rimwe na rimwe ndetse no guterana muburyo bwa datum. Uru rwego rwo guhuza rugabanya igihe cyose cyo gukora nigiciro, guhindura ibishishwa bibisi byuzuye, byuzuye-neza neza.
Byukuri-Isi Porogaramu no Gukoresha nabi
8620 ishoramari ryerekana mubikorwa bisaba intangiriro ikomeye kandi ikomeye, idashobora kwihanganira kwambara. Tekereza ku mibiri ya hydraulic, aho ibyambu byimbere bikenera ubuso bukomeye kugirango birinde isuri ituruka kumazi, ariko umubiri ukeneye imbaraga zo guhangana nigitutu. Cyangwa ibintu bimwe na bimwe bitari magnetiki sensor aho ibintu byayo ari byiza. Nubwo bimeze bityo ariko, ni amahitamo mabi ya serivise yubushyuhe bwo hejuru cyangwa ibidukikije byangirika cyane - aho niho hinjira nikel cyangwa cobalt ishingiye ku mavuta, uduce twa QSY ibikoresho na byo bikubiyemo.
Gukoresha nabi ni ugukoresha aho bikenewe-gukomera. 8620 mubyukuri icyuma gikomera. Nabonye ibishushanyo bisaba 8620 casting kugirango bikomere kuri HRC 40. Irashobora gukorwa, ariko ntabwo ukoresha ibyiza byayo byambere, kandi ushobora guhabwa serivisi nziza hamwe n amanota 4140 cyangwa 4340 yabigenewe. Icyemezo kigomba gutwarwa nimikorere, ntabwo kumenyera gusa.
Kubara ubukungu nabyo bifite akamaro. Kuburyo bworoshye, bunini, guhimba cyangwa no gutunganya ibicuruzwa byabigenewe bishobora kuba bihendutse. Agaciro ka aisi 8620 gushora imari ifunguye hamwe na geometrike igoye, isaba imashini nini cyangwa guteranya ibice byinshi ukundi. Igiciro cyo gukoresha ibikoresho byambere imbere yibishashara bifite ishingiro no kugabanuka kumashini yo hasi no gukora imirimo.
Kuyobora Guhitamo Abatanga isoko
Guhitamo utanga isoko kuri 8620 gushora imari ntabwo ari ukubona amagambo gusa. Ni ubugenzuzi bwa tekiniki. Ugomba kubaza kubijyanye nuburambe bwabo bwihariye hamwe nicyuma giciriritse: Ni ubuhe buryo busanzwe bwo kugenzura kwinjiza? Nigute bashushanya amarembo kuriyi mavuta? Bashobora gutanga raporo ya metallurgjiya harimo ingano yingano hamwe nigeragezwa rya bande? Ubushake bwumuguzi bwo kuganira kuri aya makuru ni ikimenyetso cyiza cyimbitse.
Kuramba kw'isosiyete murwego, nkamateka ya QSY yimyaka 30, akenshi bifitanye isano nubumenyi bukusanya ibibazo. Birashoboka ko bahuye-kandi bagakemura-ibibazo bya gaze ya gaze mubice byimbitse cyangwa kugera kubutaka bwuzuye neza kumurongo utoroshye. Ubunararibonye busobanura ibintu bitunguranye mugihe cyo gukora.
Hanyuma, reba kwishyira hamwe. Umufatanyabikorwa mwiza ayobora urugendo kuva icyuma gishongeshejwe kugeza igice cyarangiye. Ibi bireba kubazwa. Niba havutse ikibazo cyo kuvura ubushyuhe, nta kudasobanuka niba byari imiterere ya casting cyangwa cycle yo kuvura ubushyuhe. Kubice byingenzi, ubu bugenzuzi buva kuri Igikonoshwa gukora imashini ya nyuma ntabwo ari ibintu byiza; nibyingenzi kugirango tugere kumikorere ihamye AISI 8620 ishoboye gutanga.
